question 83

Multiple Choice

Express the function in the formss the function in the form f(x) $$f ( x ) = a ( x - h ) ^ { 2 } + k$$ k a nd indicate the vertex.
- $$f ( x ) = x ^ { 2 } - 4 x + 8$$

• A) \(f ( x ) = ( x + 2 ) ^ { 2 } + 20\)
• vertex: \(( - 2,20 )\)
• B) \(f ( x ) = ( x - 2 ) ^ { 2 } + 4\)
• vertex: \(( 2,4 )\)
• C) \(f ( x ) = ( x - 2 ) ^ { 2 } - 4\)
• vertex: \(( 2 , - 4 )\)
• D)f(x)= (x + 4)2 + 40 vertex: (-4, 40)
